ARTHUR C. FRON, OF NEW YORK, N. Y.

CARVING AND DELINEATION MACHINE.

SPECIFICATION forming part of Letters Patent No. 679,120, dated July 23,1901. Application filed March 5,1901. Serial No. 49,744. (No model.)

T0 all whom t may concern:

Be it known that I, ARTHUR C. FRON, a citizen of the United States, anda resident of the city of New York, borough of Manhattan, in the countyand State of New York, have invented a new and Improved Carving andDelineation Machine, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improved carving anddelineation machine, which is simple and durable in construction, veryeffective in operation, and arranged to accurately draw right and lefthand figures or to carve blocks right or left handed, according to apredetermined facsimile or pattern.

Theinvention consists of novelfeatures and parts and combinations of thesame, as will be fully described hereinafter and then pointed out in theclaims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews. Figure lis a plan view of the improvement arranged forreproducing line drawing in a reversed position. Fig. 2 is a sectionalfront elevation of the same on the line 2 2 in Fig. 1. Fig. 3 is a sideelevation of the same with the guideway in section. Fig. 4: is asectional front elevation of a modified form of the improvement arrangedfor carving a block according to a predetermined pattern. Fig. v5 is aside elevation of the device shown in Fig. 4, being on a reduced scale;and Fig. 6 is a section on line 6 6 in Fig. 1.

The improved carving and delineation machine illustrated in Figs. l, 2,and 3 consists, essentially, of a guideway A, adapted to be fastened toa ceiling or other suitable support, and in said guideway is mounted toslide a pivot B for arms C C', extending from said pivot in oppositedirections relativelyT to the guideway A, as is plainly illustrated inFig. l. The free ends of the arms C C' carry a tracer D and a pencil orother tool D', of Which the tracer D is intended to follow the lines ofthe figure E to be reproduced by the pencil or tool D', as indicated atE' in Fig. l. Links F F' are pivotally connected with a pivot G, iittedto slide in the guideway A, and

said links F F' are pivotally connected by braces H H with a pivot I,likewise fitted to slide in the guideway A. The pivots B, G, and I canbe of any suitable construction, but I preferably employ bolts providedwith winged nuts, as shown in the drawings. The heads of these boltswork in the recess of the guideway, and to the bolts after passingthrough the slot of the said guideway the arms are pivoted. Washers areplaced upon the bolts for spacing the arms from each other and from theguideway.

It is evident that when the operator follows with the tracer D the linesof the design to be reproduced, then the arm C is caused to slideforward and backward by the movement given to the arm by the operator,the pivot B guiding the movement of the arm in the guideway A; but asthe said arm C is pivotally connected with the link F and the latter ispivotally connected by the brace H with the pivot I, and the latter andthe pivots G and B are common to the arin IO', the link F', and the armII', it is evident that a movement identical to the one given to thetracer D is given to the tool or pencil D', so that the latter draws theiigure E', but in a reverse direction to the one shown at E.

If it is desired to produce a plurality of iigures of one kind only, itis first necessary to reproduce from the original design a reverseddesign and then use this as a pattern for reproducing a desired numberof iigures corresponding to the original design.

In order to facilitate the movement of the arms C G', the links F F',the braces I-I H', and their pivots B, G, and I, I prefer to connect thepivot B with one end of a spring J, attached to a clamp K, adjustablyheld in the guideway A.

In the arrangement shown in Fig. t a block E2 is employed,on whichoperates the tracerD, which in the present instance is a cutting-tool tobe manipulated by the sculptor to sculpture the block E2, While thecarving-tool D' operates on the block E3 to reproduce the ornamentationon the block E2. The tracer D and the carving-tool D' may be bothrotated, and for this purpose each is provided with a pulley P,connected by a belt P' with suitable machinery forimparting a rotarymotion to the tracer and the carving-tool, so that the IOO latterreadily cuts the block, and the ornamentation on the pattern isreproduced, but in a reversed position.

The arms C C', the links F F', and the braces H I-I, with their pivotsand guideway, remain the same, as above described, the guideway,however, being mounted to slide vertically, and for this purpose isprovided with suitable rods L, mounted to slide vertically in bearingsN, attached to a ceiling or other support. It is to be understood that asuitable number of guide-rods L are to be employed to properly supportthe guideway A. A spring or springs O, connected with the arm Of,supports the latter in the proper position and at the same time allowsraising and lowering of the guideway and the parts carried thereby, soas to permit the tracer to readily follow the configuration of the blockand to allow the carving-tool D' to cut the block E3 accordingly forreproducing the ornamentation, as above mentioned.

The device is Very simple and durable in construction, is easilymanipulated by the designer or carver, and accurately reproducesdrawings or relief orother patterns, but in a reversed position, asabove described.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. A carving or delineation machine, comprisinga pair of arms connected with each other and carrying a tracer and atool, a pair of links pivotally connected with each other and with saidarms, a pair of braces pivotally connected with each other and with saidlinks between their ends, and a guidewayin which the connecting-pivotsof said arms, links and braces are mounted to slide in a straight line,said arms, links and braces extending at opposite sides of saidguideway, as set forth.

2. A carving or delineation machine, comprising a pair of arms connectedwith each other and carrying a tracer and a tool, a pair of linkspivotally connected with each other and with said arms, a pair of bracespivotally connected with each other and with said links, a guideway inwhich the connectingpivots of said arms, links and braces are mounted toslide in a straight line, said arms, 5o

links and `braces extending at opposite sides of said guideway, andmeans by which the guideway and the parts carried thereon may beadjusted vertically, as set forth.

3. A carving or delineation machine, comally connected with each otherand with said 6o links, a guideway inwhich the connectingpivots of saidarms, links and braces are mounted to slide in a straight line, saidarms, links and braces extending at opposite sides ot' said guideway,and a spring for supporting said arms, links, braces and guideway, asset forth.

4c. A carving or delineation machine, comprising a pair of armsconnected with each other and carrying a tracer and a tool, a pair oflinks pivotally connected with each other and with said arms, a pair ofbraces pivotally connected with each other and with said links, theconnecting-pivots of the said arms, links and braces being mounted toslide in a straight line, and a spring pressing one of said pivots, asset forth.

5. A carving or delineation machine, comprising a guideway adapted to besuspended in a horizontal position, a pair of arms pivoted together andhaving their pivot sliding in the guideway, one of said arms carrying atracer and the other a tool, a pair of links pivoted together and havingtheir pivot sliding in said guideway, the free ends of the links beingpivoted to the arms near their outer ends, and braces pivoted togetherand having their pivot sliding in the guideway, the other ends, of thebraces being pivoted to the links between their ends, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ARTHUR c. FRON.
